Do I need to overclock Ram if I overclock Cpu?

Hello, I am planning to purchase a ryzen 3 1200.
In YouTube videos I saw that if i overclock ryzen 3 1200 to 3.8ghz then I will have to overclock the ram to get better performance in gaming. But the ram that they overclock was 2400mhz and they overclocked it to 3200mhz.

So my question is that if I overclock ryzen 3 1200 to 3.7ghz or 3.8ghz and I have 8gb 3000Mhz ram. Do I still need to overclock my 3000mhz ram?

Also I will use Asus Prime B350M K motherboard.
